Application

A direct bandgap semiconductor (bandgap 1.56 eV at 300 K). CdTe is also a strong solar cell material. It is usually sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Typically, CdTe cells use a n-i-p structure.

Synthesis of ZnO Aggregates and Their Application in Dye-Sensitized Solar Cells

One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.
